You might have better luck with app_conference (see the wiki) under UML.. It is probably a little more tolerant of loose timing and scheduling.

Hi *,
[this goes to [EMAIL PROTECTED] and [EMAIL PROTECTED]
i try to setup an VoIP conferencing server within a UML using asterisk and it's 'MeetMe conference bridge'. I have several UMLs running other services, but my asterisk know-how is poor (as you will see ;-).
Question #1: did anybody successfully implement an asterisk MeetMe-conference inside a 2.6-UML?
It needs a special "zaptel timer". As there is no special hardware, i have to use a ztdummy/2.6 or zaprtc:
<http://www.voip-info.org/tiki-index.php?page=Asterisk%20timer>
Question #2: is there any chance that either "ztdummy" or "zaprtc" will work inside 2.6-UML?
I tried "ztdummy". After frickeling the Makefile, it compiled against the UML source tree, it loads within the UML on top of zaptel.ko
[EMAIL PROTECTED] asterisk]# lsmod Module Size Used by
ztdummy 2628 0 zaptel 227940 1 ztdummy
(no other modules loaded). Asterisk works (e.g. i can hear the "conf-
onlyperson" message when i enter the conference room). But the audio of the conference itself is extremly snatchy. That _may_ be a config problem, but a very similar configuration on a non-UML works, and un-
loading the ztdummy.ko on that system results in the same snatchy audio, so i suspect the ztdummy.ko or some device configuration is broken in my UML.
At the same time, i observe this
<http://seclists.org/lists/linux-kernel/2004/Oct/8108.html>
problem within my UML, too:
# tail -f /var/log/messages tail: cannot read realtime clock: Unknown error 516
and tail exits with code 1.
Question #3: is there a problem with the RTC in 2.6.9?
My host is 2.6.8.1 + skas3-2.6.7-v5 without module support: CONFIG_SMP=y (host is a P4 with HT) CONFIG_SCHED_SMT=y CONFIG_HPET_TIMER=y CONFIG_HPET_EMULATE_RTC=y CONFIG_RTC=y CONFIG_PREEMPT=y
My guest is 2.6.9, with module support. Besides the zaptel modules no feature is compiles as a module but static.
CONFIG_UML_REAL_TIME_CLOCK=y
Question #4: Shall i try different SMP/HT/RTC settings on host or guest?
Regards, /nils.
